Let's divide 902913 by 80
Let's see how many times 80 fits into 902913.

Let's proceed to step 1:
9 divided by 80 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 80

Moving on to step 2:
80 goes into 90 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 80 from 90 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 80

On to step 3:
When dividing 102 by 80, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 11.0
If we take 80 away from 102, we end up with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 80

Advancing to step 4:
The number 80 fits into 229 2 times, leaving a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 160 from 229 leaves us with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 80

Step 5:
If we divide 691 by 80, we get 8 and a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
Deduct 640 from 691 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 80

On to step 6:
The number 80 fits into 513 6 times, leaving a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 11286.0
Deduct 480 from 513 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
The number 80 fits into 330 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 11286.4
If we subtract 320 from 330, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
80 goes into 100 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 11286.41
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 11286.412
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11286.4125
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11286.4125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11286.4125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 11286.4125 with a remainder of 0.0.
